IDE 1.6.4 compilation stuck

Hi,

I have an application reading ADS1220 A-to-D by Arduino 1.6.4 Mega 1280 SPI.
(The original Protocentral_ADS1220 test program).

While it compiles (and runs) nicely in my Program Files / Arduino folder where all libraries are, it stops (freeze) compiling towards the end when run in another folder (example in My Documents/Projects).

I guess there is something wrong with a library location or version, but I could not figure out what it was.

I attach here the compiling verbose data that shows where the compiling halts.
Can anyone tell me what is wrong?
Thx
